It carries in between the support frames 13 standingly arranged by the conveyor 11 which rotates the inside of the chamber 10 (arrow N1). Then, while the gutter holder 4 is conveyed by the upper and lower conveyors 11 in the drying chamber 10 (arrows N2 to N5), the raw laver m spread on the gutter 3 is dried, and then the lower part of the front stage 1 or the drying chamber The dried sheet-shaped dry seaweed m is peeled off from the cocoon at the peeling portion 7 provided near the exit 10, then the cocoon 3 from which the dry seaweed m has been peeled off is washed by the washing portion 8, and the heel holder 4 is made again. The sheet is conveyed toward the section 5 (arrow N6), and the above-described paper making and dehydrating operations are repeated.

  Next, with reference to FIG. 2, the structure of the hut 20 which comprises a laver production system with a laver production apparatus is demonstrated. A first fan F <b> 1 for exhaust that exhausts the exhaust gas blown up from the drying chamber 10 to the outside of the cabin is provided at the ceiling of the cabin 20. A warmer 21 is provided on the side of the hut 20. The warmer 21 has a heating means 22 such as a burner and a second fan F2 for introducing outside air for introducing low-humidity outside air into the cabin 20. The warmer 21 communicates with the interior of the cabin 20 through the duct 23. Accordingly, the low-humidity dry and cold outside air introduced into the warmer 21 by the second fan F2 is heated by the heating means 22 to become hot air and is introduced into the cabin 20 (arrow A).

  In FIG. 2, an air heating device 30 is provided on the side of the drying chamber 10. The air heating device 30 is provided with a burner 31, a heat exchange duct 32, a third fan F3 for introducing air, and the like. The heat exchange duct 32 communicates with a chimney 33 for discharging exhaust gas to the outside. The air heated by the air heating device 30 is sent to the lower portion of the drying chamber 10 (arrow B) from the communication port 12 (see also FIG. 1) opened at the lower portion of the drying chamber 10, and the interior of the drying chamber 10 is moved upward. It blows up (arrow C) and is discharged as exhaust gas to the outside of the cabin by the first fan F1 (arrow D). When the air heated by the air heating device 30 blows up the inside of the drying chamber 10, it takes away moisture from the raw laver m spread on the basket 3, and is exhausted to the outside of the hut 20 as a high-humidity exhaust gas. (Arrow D). A part thereof is directed upward of the air heating device 30 (arrow E), is reintroduced into the air heating device 30 and heated again, and is sent from the communication port 12 to the lower portion of the drying chamber 10 (arrow B).

  A humidity sensor S as a humidity measuring means is provided at an appropriate place (in the present embodiment, on the lower side) in the drying chamber 10. In FIG. 3, a humidity sensor S as a humidity measuring unit, and drivers 41 and 42 for the first fan F1 and the second fan F2 are connected to the control unit 40. The humidity inside the drying chamber 10 is measured by the humidity sensor S, and the measurement result is transmitted to the control unit 40. The first fan F1 and the second fan F2 can share a common driver. The control unit 40 controls the drivers 41 and 42 so that the air volumes of the first fan F1 and the second fan F2 have a parameter relationship. That is, when the amount of air exhausted to the outside of the cabin 20 by the first fan F1 is large, the amount of outside air introduction air into the cabin 20 by the second fan F2 is also increased. Further, when the amount of air discharged to the outside of the cabin 20 by the first fan F1 is small, the amount of outside air introduced into the cabin 20 by the second fan F2 is also reduced.

  A laver production system comprising a hut and a laver production apparatus has the above-described structure. Next, an operation method will be described. In FIG. 2, the warm air (arrow B) sent from the air heating device 30 to the lower part of the drying chamber 10 blows up inside the drying chamber 10 (arrow C), deprives moisture contained in the raw laver m, and becomes exhaust gas. The first fan F1 is discharged to the outside of the cabin 20. The humidity inside the drying chamber 10 is measured by the humidity sensor S, and when the humidity in the drying chamber 10 is excessively high and becomes excessively humid, the rotational speed of the first fan F1 is increased to increase the humidity. Is increased, and the rotational speed of the second fan F2 is increased, and the amount of air introduced into the hut 20 by the second fan F2 is increased. As a result, the humidity in the overhumid drying chamber 10 is quickly reduced to normal humidity.

  On the contrary, when the humidity measured by the humidity sensor S is too low, the rotational speed of the first fan F1 is decreased to reduce the exhaust air volume of exhaust gas discharged outside the hut 20 and the second The rotational speed of the fan F2 is also reduced, and the air volume of the outside air introduced into the cabin 20 is also reduced. As a result, the humidity in the drying chamber 10 that has decreased excessively is quickly returned to normal humidity.

  As described above, while the humidity in the drying chamber 10 is measured by the humidity sensor S, the control unit 40 controls the first fan F1 and the second fan based on the humidity data that is the measurement result transmitted from the humidity sensor S. By controlling the rotation speed (air volume) of the fan F2, it is possible to appropriately maintain the humidity of the drying chamber 10 and more appropriately dry the raw nori m to produce high quality dry nori.

  As described above, the humidity and temperature of the drying chamber are in a parameter relationship that correlates with each other. When the humidity is low, the temperature is high, and when the humidity is high, the temperature is low. Therefore, in this embodiment, the humidity management of the drying chamber is performed based on the measurement result (humidity data) of the humidity sensor. However, instead of the humidity sensor, a temperature sensor is provided as a temperature measurement means, and the measurement result of the temperature sensor is provided. The air volume adjustment by the first fan F1 and the second fan F2 may be performed based on (temperature data).

  That is, when the temperature measured by the temperature sensor is high, the drying chamber 10 is in a high temperature state. Therefore, by increasing the air volume of the first fan F1 and the second fan F2 and introducing a large amount of outside air, the drying chamber 10 has a high temperature. Reduce the temperature. When the temperature measured by the temperature sensor is low, the drying chamber 10 is in a low temperature state, so the air volume of the first fan F1 and the second fan F2 is decreased to increase the temperature in the drying chamber 10.

  In the present embodiment, the second fan F2 for introducing the outside air is installed in the warmer 21 provided with the heating means 22, but the warmer 21 provided with the heating means 22 is not necessarily required and is cold. You may make it introduce | transduce into the hut 20 by the 2nd fan F2 without heating external air.

  This is particularly useful for a laver production system in which a laver production apparatus installed inside a hut is used to produce a sheet-like dry laver by drying raw laver while conveying a cocoon holder through a drying chamber.
